The impact of roads on the flora and fauna of Neotropical rainforest is perhaps the single biggest driver of habitat modification and population declines in these ecosystems. We investigated the road-edge effect of a low-use dirt road on amphibian and reptile abundance, diversity, and...

Red-cockaded woodpecker (Picoides borealis) translocations have been used to bolster woodpecker populations and to fill breeding vacancies. Artificial, insert cavities have been used to offset cavity shortages in woodpecker clusters and are the primary cavity type used in recruitment clusters in Texas and Arkansas, but inserts may lose their...

Partial brood loss in red-cockaded woodpeckers (Picoides borealis) was studied during 2 breeding seasons in eastern Texas. The timing of partial brood loss, group size, number of initial nestlings, number of birds fledged, and habitat characteristics of the group's cavity-tree cluster were examined for 37 woodpecker groups in loblolly- (

Red-cockaded woodpecker populations declined precipitously following European settlement and expansion and cutting of the original pine forests across the southeastern United States. By 1990 most residual populations lacked demographic viability, existed in degraded habitat, and were isolated from other populations. The primary causes of this situation were harvest of...

Red-cockaded woodpeckers (Picoides borealis are known to be regular members of mixed species foraging flocks. We censused avian species associated with foraging red-cockaded woodpeckers in longleaf pine (Pinus palustris) habitat and in mixed loblolly pine (P. taeda)-shortleaf pine (P. echinata

An increased ability to analyze landscapes in a spatial manner through the use of remote sensing leads to improved capabilities for quantifying human-induced forest fragmentation. Developments of spatially explicit methods in landscape analyses are emerging. In this paper, the image delineation software program eCognition and the spatial pattern analysis program...

We conducted this assessment to provide information on the current conditions of riparian and wetland ecosystems in reference to their natural range of variability on the Manti-La Sal National Forest during forest plan revision. We used peer-reviewed literature, data from the Forest and other partners, and site visits to evaluate the status of four key ecosystem...

In road construction projects across the United States, erosion control methods (e.g., erosion control blankets [ECBs]), are mandated to stimulate seedbed regeneration and prevent soil loss. Previous reports have suggested that snakes are vulnerable to entanglement in ECBs. We conducted a literature review, field surveys, and an entanglement experiment to examine what...

During a 2-year study we examined arthropod communities (density and biomass) on longleaf pines (Pinus palustris) in eastern Texas during spring, summer, and winter on trees in 3 age classes: 40-50, 60-70, and 130-1 50 years, as a potential food source for the red-cockaded woodpecker (Picoides borealis). We also examined arthropod...

Red-naped sapsuckers (Sphyrapicus nuchalis) are functionally important because they create sapwells and cavities that other species use for food and nesting. Red-naped sapsucker ecology within aspen (Populus tremuloides) has been well studied, but relatively little is known about red-naped sapsuckers in conifer forests. We used light detection and ranging (LiDAR) data...

This assessment was conducted to provide information on the current conditions of riparian, wetland, and groundwater-dependent ecosystems in reference to their natural range of variation on the Salmon-Challis National Forest during forest plan revision. We used peer-reviewed literature, data from the Forest and other partners, and site visits to evaluate the status of...

The adaptation of red-cockaded woodpeckers (Picoides borealis) to fire-maintained southern pine ecosystems has included the development of behaviors that permit the species to use living pines for their cavity trees. Their adaptation to pine ecosystems has also involved a major adjustment in the species' breeding system to cooperative breeding,...

Sexual divergence in foraging behavior exhibited by red-cockaded woodpeckers (Picoides borealis) should reduce intersexual competition for foraging sites. Males tend to forage at greater heights and on smaller stem diameters than females. It is well known that red-cockaded woodpeckers have an aversion to a well-developed stratum of midstory...
